Abstract
Disclosed is a blast furnace iron storage type iron tap channel slag skimmer capable of being recycled partially. The slag skimmer is located at the tail end of a main channel body of an iron tap channel. A slag channel is formed in the upper portion of the front side of the slag skimmer. The bottom end of the slag skimmer and a channel bottom form an iron tap passage. The slag skimmer comprises upper-lower combined type base bodies. A plurality of semicircular convex blocks are arranged on the bottom face of the upper base body. A plurality of semicircular grooves are formed in the upper surface of the lower base body correspondingly. The upper base body and the lower base body are connected in a matched mode. The bottom end of the lower base body is provided with a trapezoidal flow passing opening. A square inner cavity is formed in the lower base body and communicates with the upper surface of the trapezoidal flow passing opening. A high-strength anti-cracking pouring layer is formed in the square inner cavity in a pouring mode. Maintenance and replacement are convenient, and the service life is long.
Description
Technical field
The present invention relates to a kind of slag skimmer, particularly relate to the slag skimmer of a kind of slag sluicing system in blast furnace iron storage type iron tap channel tap drain, belong to metallurgy industry.
Background technology
Playing the parts of slag sluicing system effect in being placed on tap drain when slag skimmer is blast furnace casting, its profile is as it is shown in figure 1, molten iron density is bigger than slag, and molten iron flows out from slag skimmer lower passage, and scum is positioned at top and flows out from slag runner mouth, has thus reached the purpose of slag sluicing system.
Iron storage type ditch is owing to containing molten iron in tap drain, especially near slag skimmer position, molten iron is more, owing to the cushioning effect of molten iron is to slag skimmer upper impingement power little when tapping hole puts molten iron, top is corroded the least, corrodes serious position and is predominantly located at the molten iron passage of slag skimmer bottom, after slag skimmer terminates service life, severity is corroded in bottom often, and top is the most intact, can be continuing with completely.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that a kind of convenient maintenance and replacement, service life length slag skimmer.
For realizing the object of the invention, provide techniques below scheme: a kind of can the blast furnace iron storage type iron tap channel slag skimmer of partially recycled utilization, described slag skimmer is positioned at iron tap channel tap drain tail end, described slag skimmer front side top offers slag runner, slag skimmer bottom constitutes, with bottom of trench, the passage that taps a blast furnace, it is characterized in that slag skimmer includes upper and lower combination type matrix, upper matrix bottom surface is provided with several semicircle projections, lower substrate upper surface correspondence offers several semi-circular recesses, base mate connects up and down, described lower substrate bottom offers trapezoidal head piece excessively, square cavities is offered in lower substrate, square cavities connects with trapezoidal head piece upper surface of crossing, high intensity crack resistence pouring layer it is cast with in square cavities.
As preferably, trapezoidal head piece inner surface of crossing is provided with zirconium matter layer.
As preferably, zirconium matter layer thickness is 20 ~ 30mm.
As preferably, trapezoidal head piece height of crossing is 10 ~ 20mm.
As preferably, semicircle projection center is inserted with reinforcement plug.
As preferably, the height of upper matrix is the 1/3 of lower substrate.
As preferably, the height of slag skimmer is 800mm.
The method have the benefit that slag skimmer is divided into upper and lower two parts by the present invention, the raw material that upper basic material can be done class low spot makes, it is ensured that can reuse 1 time the most permissible, lower substrate design of material is with as original, it is necessary to assure service life normally.Having gap between after placing in view of two slag skimmer stackings, we devise two semicircular tongue and grooves at two slag skimmer joint faces, and the fissure of displacement connects, and slag ferrum problem is crossed in the gap the most well solving slag skimmer.

Fig. 1 is front view of the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the scheme of installation of Fig. 1.
